Thread: 80lb injector data help

  1. #1

    80lb injector data help

    In the Greg Banish CD he has injector data for the cobrajet siemen deka 80lb injectors. Are these the same siemen deka 80lb injectors the injector venders sell? Or would the cobrajet injectors have different injector data?

    here's the information from the injectors I'm looking at and wondering if I can use the Greg Banish injector data.

    80lb/h Siemens Deka 4 Mototron High Impedance (Long Style) EV1 Connector

    Genuine Siemens / Mototron DEKA IV ( DEKA 4 ) High Impedance Injectors

    Cross References:
    Siemens FI114992
    Siemens 110324


    ◦Model: FI114992
    ◦Manufactured by: Siemens Deka

    OK I found out they're the same injectors but I also have heard the Greg Banish injector data for these injectors is going to create a rich idle that won't respond to a ve change and also a extremely lean tip from the pcm pulling fuel at idle?

    Can someone weigh in with some help or personal experience?
    Thank You

    That's all true!

    When you run injectors of that size, the numbers aren't drop-in; you really have to tune short pulse.

    Thanks is there any information on how to tune short pulse? It's the short pulse adder table?
